Therefore, GCD of numbers 15, 865, 773, 475 is 1

Given Input Data is 15, 865, 773, 475

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 15 is 3 x 5

Prime Factorization of 865 is 5 x 173

Prime Factorization of 773 is 773

Prime Factorization of 475 is 5 x 5 x 19

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(15, 865) = 2595

GCD(15, 865) = ( 15 x 865 ) / 2595

GCD(15, 865) = 12975 / 2595

GCD(15, 865) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 773

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 773) = 3865

GCD(5, 773) = ( 5 x 773 ) / 3865

GCD(5, 773) = 3865 / 3865

GCD(5, 773) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 475

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

GCD(1, 475) = 475 / 475

GCD(1, 475) = 1

GCD of 15, 865, 773, 475 is 1
